To @ZZ whom it ntfty concern:

Be it-known that I, FRANK HWELCH, a citizen of the United States, residing at NewYork, (Brooklym) in the county of Kings and State of New York, have invented certain new and useful Improvements in Mud-Guards for Bicycles, of which the following is a full and complete specication, such as will enable those skilled in the art to which it appertains to make and use the same.

This invent-ion relates to mud-guards for bicycles, and it has specific relation and adaptation to an improved guard which is designed for the main drive-sprocket and chain of the crank-shaft.

One object of my invention is to provide a mud-guard for said drive-sprocket and chain which will be adapted in a special manner for a plurality of adjustments in a lateral plane with respect to the crank-shaft, in a longitudinal plane or direction with respect to the crank-shaft, and in an independent movement with respect to the periphery of the sprocket-wheel, whereby said device may be conveniently applied to and electively used on various sizes of bicycles and accurately adjusted in position with respect to diterent diameters of sprocket drive-wheels.

A further object ot' my invention is to provide an improved device of the specific character just stated which will be very simple and inexpensive and which can be conveniently applied and operated.

In the drawings forming part of this speciiication, in which like reference characters denote like parts in the several views, Figure l is a side View showing my improved drivesprocket andv chain mud-guard in operative position with relation to the bicycle-frame and driving mechanism. Fig. 2 is a front end View of the subject-matter illustrated in Fig. l. Fig. 3 is a detail side View illustrating the variable adjustment of my improved mud-guard device on a plane lateral with respect to the longitudinal plane of the driveshaft or to and from the latter, and also showing the independent adjustment with respect to the periphery of the sprocketwheel. Fig. d is a detail top or plan view illustrating the adjustment of the device in a plane or direction longitudinal with respect to the crank-shaft or lateral with respect to the sprocket-gear.

Referring to the drawings, A designates a clam p, which is essentially cylindrical or ringshaped and which preferably consists of two at the side of which operates the sprocket drive-gear, (represented at F.) It will be noted that the relative construction and arrangement are such that the cylindrical clamp or ring A is adjustable or slidable longitudinally up and down upon the frame-bar D, that it is also adj ust-able or turnable in a lateral movement upon said frame-bar, and that it may be tightly bound or secured in any position longitudinally or laterally with respect to theframe-bar D, to which it may be adjusted.

' The shield G, which is of usual segmental contour, is carried upon and by the ring or clamp A, the connection being preferably formed by having the frame or arms which carry the shield G in projecting position received between the projecting front ends 72. of the half members b of the clamp A, the front part of the clamp being adjustably connected by means of a bolt and nut or setscrew adjusting device, as indicated at t, similar to the rear adjustable connection c.

Preferably the frame which sustains the shield G in projecting position lconsists simply of two divergent arms kk, which are connected at their outer ends to the inner side of the segmental shield G. (See Figs, 2 and It.) These arms 7c lo extend at an angle downwardly and beyond the plane of the shield G, so that their convergent terminal ends which form the connection with the clamp A are on a plane within the plane occupied by the shield G. Said arms 7c k may be formed of a single piece of wire bent centrally to form an eye or loop, as represented at l in Figs. 2 and 3, which embraces the securing bolt or ICO screw at the front end of the clamp device and forms a turning bearing thereon.

From the foregoingdescription of the general construction and arrangement it will be noted that the shield G is of course carried in both the longitudinal and lateral adjustments of the clamp device A upon the frame-bar D, whereby said shield is adjusted laterally with respect to the sprocket-gear F and also to and from the periphery of the latter, While the turnable connect-ion of the supporting-arms 7c 7c With the claxnpdevice A, as just above described, enables an independent swing or adjustment of the shield G, with respect to the periphery of the sprocket-gear F Without movement or variation of the position of the main clamp device A.

The shield G occupies a plane away from or beyond the plane of the clamp device A, which is secured to the frame member D, as shown in Figs. 2 and 4, by reason of the inclination or bends of the arms 7o 7o, whereby said shield is projected into proper relative position with respect to the sprocket-gear which is at the side oi' the frame-bar D. When the arms -c 7c are formed of wire, as herein shown and described, theymay be readily and conveniently bent, as desired, to enable the perfect adjustment of the shield G With respect t-o the sprocket-gear under circumstances concerning anyspecific size or kind of bicycle mechanism or the degree of space which may exist between the sprocketgear and the frame member D, upon which the clamp device is slidably and adjustably carried. If desired, the inner faces of the front ends h of the half members Zi of the clamp A may be serrated or roughened, as indicated at m in Fig. 4, to more tightly bind or clamp the eye Z, which forms the turnable connection of the arms la with the clamp device. The ring or cylindrical clamp may be interiorly provided with a cushion, as shown at o in Fig. 4, to preventmarring of the surf face of the cylindrical frame-bar D. The

operation and advantages of my invention Will be readily understood.

The device is adapted for convenient and effective application to various sizes of bicycle mechanisms and can be readily adjusted in various directions. The adjustment of the clamp A in a longitudinal direction upon the frame member D will of course carry with it the shield G in such adjustment, While the shield is independently adjustable with relation to the clamp and without movement of the latter. The adjustment of the clamp in a lateral pla-ne with respect to the frame-bar D by simply turning the clamp upon the bar will also carry the shield G in such adjustment. The perfect adaptation of the gear to various sizes of sprocket drive-Wheels and in relation to various sizes of frames is thus permitted.

Having fully described my invention, 'I claim as new and desire to secure by Letters Patentl. An improved adjustable mud-guard for the sprocket drive-Wheels of bicycles, comprising a cylindrical or ring-shaped clamp adapted to be adjusted laterally and longitudinally upon the cylindrical frame-bar of the bicycle, and a shield having a pivotal connection with said clamp and projecting therefrom on a lateral plane with respect thereto, substantially as and for the purpose set forth.

2. An improved mud-guard for the sprocket drive-Wheels of bicycles, comprising a cylindrical or ring-shaped clamp adapted to be adjusted longitudinally and laterally upon a cylindrical framebar of the bicycle and having half members provided with projecting front ends, a shield carried by arms formed with a loop at their meeting termini, which loop is received between said meeting ends and by which said shield is independently adjustable upon and with relation to the clamp, and an adjusting bolt orscrewpassing through said meeting ends and loop, substantially as and for the purpose set forth.A

3. An improved adjustable mud-guard for the sprocket drive-Wheels of bicycles, comprising a clamp adapted to be adjusted lata erally and longitudinally upon andwith re-v spect to the frame-bar of the bicycle, means for securing said clamp in adjusted position,

.a shield carried upon members projecting out- Wardly and laterally from one end of said clamp, said shield-carrying member being adjustable upon and with relation to the clamp in a longitudinal plane with respect to the shield device, and means for securing said v shield-carryin g members in adjusted position With relation to the clamp, substantially as and for'the purpose set forth.

4. The combination, with the sprocket drive-Wheel and the upwardly and forwardly projecting cylindrical frame-bar D of a bicyi cle, of a cylindrical clamp or ring surrounding and embracing said frame-bar and adjustable longitudinally and turnable thereon, means for securing said clamp or ring in adj usted position,and a shield carried on a plane beyond and at one side of said clamp or ring and sustained by the latter, said shield having an independent adjustable movement IIO upon and with relation to said ring or clamp in a longitudinal plane with respect to the shield, substantially as shown and described. In testimony that I claim the foregoing as my invention Ihave signed my name, in pres# ence of the subscribing witnesses, this 8th day of January, 1900.
